IMHO it would be nice to have a configuration option that ensures that only $_POST, $_GET, $_SERVER, $_ENV etc. are set, and that $HTTP_POST_VARS, $HTTP_GET_VARS, $HTTP_SERVER_VARS, $HTTP_ENV_VARS etc. are not defined.

Why?
Obviously to remove the overhead of having a duplicate version of each variable.

Furthermore, this can assist in cleaner, more secure code (in my humble opinion).
For example:I just ran into a situation where a login was checked. The submitted password was removed from $_POST. It was, however, still available from $HTTP_POST_VARS. 

(Of course, this last issue could also be fixed by making one a reference to the other (as suggested in bug 15180).)

I think the phrase 'avoid duplication of volatile information' applies here.

This is fixed in PHP5 CVS.
